TO WHOM IT MAY CONOERN:

Be it known that LA PHILANDER P. LANE, of Cincinnati, Hamilton county, Unio,havc invented a. Self- Lubricating Journal-BOX, and do hereby declare the following to he a. full, clear, and exact description thereof, reference being had to the accompenying drawings, making part of this specification.

This invention relates to a journal-box so constructed as, during the rotation of the shaft, to alord n. constent supply of lubricating oil -without the use of Veither wicks or f an elevated reservoir.

Figure 1 is a. perspective view of the parts detached.

Figure 2 is a transverse section of the box.

Figure 3 is a. longitudinal section thereof. v

A is the lower member or step, and B the upper member or .cop of a. journal-box. C and D represent the Babbit" lining of cap and step respectively. The step A contains, :it its lower portion, a. chamber, E, whose upper part is preferably lower than the lowest part of the journal. F is nnarrow longitudinal slot, which extends upward from the chamber E through the bottom of the bearing. G g G" g are ducts neer theends of the step, which ducts communicate with the ledges or channels H H et the meeting of the step and cap. I is an oriice in the cap, through which oil may be supplied when desired. J represents the customary screw-bolts for fasteningthe cap. One or more circular or other apertures muy be employed instead of the slot F. A

The operation of this box is as follows: The reservoir lor chamber E being supplied with oil, the shaft is placed in the step, and the ccp screwed in place. A. few drops of oil are then poured in'to the hole I, und, the shnftbeing set in motion, oil is found to continually flow up Athrough the slot F, so as to keep the journal fully' lubricated, so long es any oil remains in the chamber E. The overplus of cil returns' along the ledges H H5 and is caught by the ducts Gr g G g and returned to the reservoir.

This plan of journal-boi avoids the expense and annoyance of wicks, clogged by the accumulated feculencies, or scorched by an overheated shaft; and it also svoidsthe flirt and waste which constantly attend the overflow of those reservoirs which orev wholly or partially above the bottom of the journal.

I claim herein as new and of my invention- The seltlubricnting journal-box, having the oil-chamber E below the bottom of the journal, and communi eating with the journal, at or near its mid-length, by one or more apertures F, und, at or'near, the ends thereof, by ducts Gr y G y', to which the overplus of oil is conveyed by the channels HH', substantially es set forth.

In testimony of which invention I hereunto set my hand. v
